摘要:

首次在光泵金刚石样品中实现了NV $^{-}$中心的激光发射。使用纳秒训练的150 ps 532 nm激光脉冲来泵浦样品。激光脉冲的中心波长为720 nm,谱宽为20 nm,脉宽为1 ns,总能量约为10 nJ。在泵浦-探测方案中,我们研究了高功率激光脉冲泵浦金刚石晶体时,由于NV $^{-}$电离和NV $^{0}$浓度增长引起的激光条件和增益饱和。

英文摘要:

For the first time, lasing at NV$^{-}$ centers in an optically pumped diamond sample is achieved. A nanosecond train of 150-ps 532-nm laser pulses was used to pump the sample. The lasing pulses have central wavelength at 720 nm with a spectrum width of 20 nm, 1-ns duration and total energy around 10 nJ. In a pump-probe scheme, we investigate lasing conditions and gain saturation due to NV$^{-}$ ionization and NV$^{0}$ concentration growth under high-power laser pulse pumping of diamond crystal.
